God said unto Abraham: "Take now thy son, thine only son Isaac, whom thou lovest, and get thee into the land of Moriah; and offer him there for a burnt-offering upon one of the mountains which I will tell thee of".

(Genesis 22:2) It is interesting here to note that Mount Moriah is inside of the walls of the present city of Jerusalem.

It was the site of the temple of Solomon, and supposed to be the very spot where Abraham was met by Melchizedek.

It is the place where Abraham was directed to offer and did offer up his son Isaac.
[97]Providing himself with wood to be used for the fire, Abraham and his son and servants journeyed for three days from the plains of Mamre to Moriah; and arriving there, he at once prepared for the burnt-offering.
Isaac was not aware of the purpose of his father to offer him; so he said to his father: "Behold the fire and the wood: but where is the lamb for a burnt offering?
And Abraham said, My son, God will provide himself a lamb for a burnt-offering." Abraham then informed his son that he was to be the offering.

Then he bound Isaac and laid him upon the altar and stretched forth his hand and took the knife with which to slay his son.
